A simple & short TAS. The goal is to complete Training Area from the title screen.
This is a 4-frame improvement over my TAS 3 years ago. 2 frames come from this new Air Dash technique I found during my X4 Zero TAS. There's another 4 frames difference due to newer emulator version, but that doesn't count as an improvement.
Edit: Now it's an 8-frame improvement. I updated the movie with another 4 frame improvement, thanks to M3's finding of cancelling ladder jump animation. Credits go to M3.
Difficulty is untouched, because it won't affect the Training Area.
Zero is chosen, because Zero can kill the boss much faster than X.
Boss is Alia Magma Dragoon, but a much weaker version than Mega Man X4, with limited moves.
Turnaround SDC (Slash Dash Cancel) is used in the boss fight, as it's faster than the regular SDC. Taking damage beforehand is necessary.

DrD2k9: Updating movie file as requested.
DrD2k9: Claiming for judging.
DrD2k9: It may not be huge, but even a small improvement to a publication is still an improvement. Accepting as an improvement to [4661] PSX Mega Man X5 "Training, Zero" by HappyLee in 01:43.32.
